From St Augustine to Machiavelli to John Kenneth Galbraith, many commentators, despite their very different worldviews, have blamed the instability of free societies on the restlessness of the human heart.

Eric Benjamin conducts the Tuscarawas Philharmonic Orchestra and Chorus as they perform selections from Handel's "Messiah" during a free performance at Sacred Heart Church in New Philadelphia on Sunday.

In science:

The notion of speciﬁc free energy lies at the heart of all of our main results.

Random Surfaces

At the heart of the argument lies an upper bound for the free energy of the deformed Gibbs measure, which is obtained by the variational principle for free energies.

Edge-reinforced random walk on a ladder

Physically, the sub ject is a topic that lies at the heart of elementary particle physics: There are about 25 free parameters in the standard model of electroweak and strong interactions, namely the coupling strengths of the three interactions, the fermion and boson masses, and various mass mixing angles.

Spatio-temporal Chaos and Vacuum Fluctuations of Quantized Fields

Finally, the 10879-dimensional has 16-dimensional source A7, and when restricted to the same maximal subgroups as the previous module, is the sum of a free module and the heart of the free module.
